   Example
   A simple example of how to append the raw image URLs to the content of any post or page that has at least one gallery.

    add_filter( 'the_content', 'wpdocs_show_gallery_image_urls' );
   
   /**
    * Show image URLs below the content
    */
   function wpdocs_show_gallery_image_urls( $content ) {
   
   	global $post;
   
   	// Only do this on singular items
   	if( ! is_singular() )
   		return $content;
   
   	// Make sure the post has a gallery in it
   	if( ! has_shortcode( $post->post_content, 'gallery' ) )
   		return $content;
   
   	// Retrieve the first gallery in the post
   	$gallery = get_post_gallery_images( $post );
   	$image_list = '<ul>';
   
   	// Loop through each image in each gallery
   	foreach( $gallery as $image_url ) {
   		$image_list .= '<li>' . '<img src="' . $image_url . '">' . '</li>';
   	}
   	$image_list .= '</ul>';
   
   	// Append our image list to the content of our post
   	$content .= $image_list;
   
   	return $content;
    }

   This does not work if the gallery type is set to ‘slideshow’. It returns nothing. Removing type=”slideshow” from the gallery shortcode allows the images to be picked up by this function.
